<h2>Detailed Description</h2>
<p>The Q3TableSelection class provides access to a selected area in a <a href="q3table.html">Q3Table</a>.</p>
<p>The selection is a rectangular set of cells in a <a href="q3table.html">Q3Table</a>. One of the rectangle's cells is called the anchor cell; this is the cell that was selected first. The <a href="q3tableselection.html#init">init</a>() function sets the anchor and the selection rectangle to exactly this cell; the <a href="q3tableselection.html#expandTo">expandTo</a>() function expands the selection rectangle to include additional cells.</p>
<p>There are various access functions to find out about the area: <a href="q3tableselection.html#anchorRow">anchorRow</a>() and <a href="q3tableselection.html#anchorCol">anchorCol</a>() return the anchor's position; <a href="q3tableselection.html#leftCol">leftCol</a>(), <a href="q3tableselection.html#rightCol">rightCol</a>(), <a href="q3tableselection.html#topRow">topRow</a>() and <a href="q3tableselection.html#bottomRow">bottomRow</a>() return the rectangle's four edges. All four are part of the selection.</p>
<p>A newly created Q3TableSelection is inactive -- <a href="q3tableselection.html#isActive">isActive</a>() returns false. You must use <a href="q3tableselection.html#init">init</a>() and <a href="q3tableselection.html#expandTo">expandTo</a>() to activate it.</p>

<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="Q3TableSelection"></a>Q3TableSelection::Q3TableSelection ()</h3>
<p>Creates an inactive selection. Use <a href="q3tableselection.html#init">init</a>() and <a href="q3tableselection.html#expandTo">expandTo</a>() to activate it.</p>
<h3 class="fn"><a name="Q3TableSelection-2"></a>Q3TableSelection::Q3TableSelection ( int <i>start_row</i>, int <i>start_col</i>, int <i>end_row</i>, int <i>end_col</i> )</h3>
<p>Creates an active selection, starting at <i>start_row</i> and <i>start_col</i>, ending at <i>end_row</i> and <i>end_col</i>.</p>
<h3 class="fn"><a name="anchorCol"></a>int Q3TableSelection::anchorCol () const</h3>
<p>Returns the anchor column of the selection.</p>
<p>See also <a href="q3tableselection.html#anchorRow">anchorRow</a>() and <a href="q3tableselection.html#expandTo">expandTo</a>().</p>
<h3 class="fn"><a name="anchorRow"></a>int Q3TableSelection::anchorRow () const</h3>
<p>Returns the anchor row of the selection.</p>
<p>See also <a href="q3tableselection.html#anchorCol">anchorCol</a>() and <a href="q3tableselection.html#expandTo">expandTo</a>().</p>
<h3 class="fn"><a name="bottomRow"></a>int Q3TableSelection::bottomRow () const</h3>
<p>Returns the bottom row of the selection.</p>
<p>See also <a href="q3tableselection.html#topRow">topRow</a>(), <a href="q3tableselection.html#leftCol">leftCol</a>(), and <a href="q3tableselection.html#rightCol">rightCol</a>().</p>
<h3 class="fn"><a name="expandTo"></a>void Q3TableSelection::expandTo ( int <i>row</i>, int <i>col</i> )</h3>
<p>Expands the selection to include cell <i>row</i>, <i>col</i>. The new selection rectangle is the bounding rectangle of <i>row</i>, <i>col</i> and the previous selection rectangle. After calling this function the selection is active.</p>
<p>If you haven't called <a href="q3tableselection.html#init">init</a>(), this function does nothing.</p>
<p>See also <a href="q3tableselection.html#init">init</a>() and <a href="q3tableselection.html#isActive">isActive</a>().</p>
<h3 class="fn"><a name="init"></a>void Q3TableSelection::init ( int <i>row</i>, int <i>col</i> )</h3>
<p>Sets the selection anchor to cell <i>row</i>, <i>col</i> and the selection to only contain this cell. The selection is not active until <a href="q3tableselection.html#expandTo">expandTo</a>() is called.</p>
<p>To extend the selection to include additional cells, call <a href="q3tableselection.html#expandTo">expandTo</a>().</p>
<p>See also <a href="q3tableselection.html#isActive">isActive</a>().</p>
<h3 class="fn"><a name="isActive"></a>bool Q3TableSelection::isActive () const</h3>
<p>Returns whether the selection is active or not. A selection is active after <a href="q3tableselection.html#init">init</a>() <i>and</i> <a href="q3tableselection.html#expandTo">expandTo</a>() have been called.</p>
<h3 class="fn"><a name="isEmpty"></a>bool Q3TableSelection::isEmpty () const</h3>
<p>Returns whether the selection is empty or not.</p>
<p>See also <a href="q3tableselection.html#numRows">numRows</a>() and <a href="q3tableselection.html#numCols">numCols</a>().</p>

<h3 class="fn"><a name="numCols"></a>int Q3TableSelection::numCols () const</h3>
<p>Returns the number of columns in the selection.</p>
<p>See also <a href="q3tableselection.html#numRows">numRows</a>().</p>
<h3 class="fn"><a name="numRows"></a>int Q3TableSelection::numRows () const</h3>
<p>Returns the number of rows in the selection.</p>

<h3 class="fn"><a name="rightCol"></a>int Q3TableSelection::rightCol () const</h3>
<p>Returns the right column of the selection.</p>
<p>See also <a href="q3tableselection.html#topRow">topRow</a>(), <a href="q3tableselection.html#bottomRow">bottomRow</a>(), and <a href="q3tableselection.html#leftCol">leftCol</a>().</p>
<h3 class="fn"><a name="topRow"></a>int Q3TableSelection::topRow () const</h3>
<p>Returns the top row of the selection.</p>
<p>See also <a href="q3tableselection.html#bottomRow">bottomRow</a>(), <a href="q3tableselection.html#leftCol">leftCol</a>(), and <a href="q3tableselection.html#rightCol">rightCol</a>().</p>
<h3 class="fn"><a name="operator-not-eq"></a>bool Q3TableSelection::operator!= ( const Q3TableSelection &amp; <i>s</i> ) const</h3>
<p>Returns true if <i>s</i> does not include the same cells as the selection; otherwise returns false.</p>
<h3 class="fn"><a name="operator-eq-eq"></a>bool Q3TableSelection::operator== ( const Q3TableSelection &amp; <i>s</i> ) const</h3>
